Methods 35 cases were performed with left ventriculogram, ascending aortogram and selective coronary arteriogram including hepatoclavicle, long axial oblique, right anterior oblique, posteroanteroposterior and latercal projections.

35例均采用肝锁位、长轴斜位、右前斜位、后前位及侧位分别进行左心室、升主动脉和选择性冠状动脉造影。

Result: The major clinical indications for transcatheter embolization included uterine atony in 12 women, a genital tract lesion in 7 women, placenta previa in 2 women, and placenta accreta in 2 women. Two patients were known to have myomas. All were already in-house.

结果：接受动脉栓塞治疗的主要的临床适应症包括十二位子宫收缩无力患者、七位生殖道裂伤患者、两位前置胎盘患者、两位黏生性胎盘患者、其中还有两位怀孕合并子宫肌瘤的患者。

Fortunately,however,computer designers have developed a method for detecting such errors by adding an extra check bit or parity bit to each 6,7,or 8-bit character represented in storage.

不过幸运的是计算机设计者已研制了一种检测这种错误的方法，这就是对在存储器中表示的每个 6 位，7 位或 8 位字符增加一个附加的检查位或奇偶检验位。

In theory, it can have an unlimited bit depth, that is, each sample point 1-8-bit, 24-bit, 32-bit or 48-bit.

在理论上它能够有无限位深，即：每样本点1-8位、 24位、32位或48位。

The company also employs a Czech brewmaster, Cuban head of quality control, Russian head of maintenance, Portuguese packaging supervisor and Scottish electrical engineer.

该公司还聘请了一位捷克裔酿酒大师，一位古巴裔质监主管，一位俄罗斯裔维修主管，一位葡萄牙裔包装监管员和一位苏格兰裔电气工程师。

Bit 6 is AC,bit 7 is carry flag,bit 4 is for register bank select and bit 5 is user controlled flag.

位6是AC，位7是进位标志，位4用作寄存器组选择，位5是用户控制标志。

This remark struck a panic terror into several who were present, insomuch that one or two of the ladies were going to leave the room; but a friend of mine, taking notice that one of our female companions was big with child, affirmed there were fourteen in the room, and that, instead of portending one of the company should die, it plainly forebode one of them should be born.

席上的几个人顿时大惊失色，有一两位女士竟欲起身离席而去。此时艾迪生的一位朋友注意到席上有一位身怀六甲的女客，便说同席的不是13人，而是14人；这不是一位客人要死的凶兆，而是一位客人要出生的吉兆。

A novel carbonyl transposition led by anilines'nucleophilic addition to methyl 2-keto α-D-glucopyranoside was discovered. And the mechanism of the reaction concerned to an enol rearrangment was provided through tracing the change of 〓H-NMR and 〓C-NMR of a hemiacetal intermediate which was obtained in the reaction of o-phenylene diamine with 2-keto glycoside. Both the intermediate and the converting product were identified by 〓H-NMR,〓C-NMR,〓H-〓H COSY and HMQC.

一、发现了2-位氧化α-甲基D-葡萄糖苷的芳胺亲核加成引起羰基转位的新方法，利用核磁共振氢谱及碳谱对邻苯二胺与2-位氧化α-甲基D-葡萄糖苷加成生成的稳定中间体半缩酮化合物在氘代丙酮中的变化进行跟踪，结合对转化产物的氢氢相关谱和HMQC结构确证，提出了该反应中2-位羰基通过烯醇化互变而转至3-位的机理并得到了验证。

The effect of upper tropospheric perturbation PV on the development of the South-West Meso-cyclogenesis is discussed on Hoskins PV Principle in terms of conservation of PV on isobaric surface and humid isentropic PV.Upper tropospheric perturbation PV,which dilates slantwise downward and southward,is found to be an important factor to influence the low-level South-West Mesocyclone.

基于Hoskins位涡理论思想从等压面位涡守恒和湿等熵位涡守恒的角度来研究对流层高层位涡扰动对低层西南涡的发生发展影响，发现对流层高层位涡扰动是影响西南涡发生发展的重要因素，它对西南涡的影响表现出它有向南向下倾斜伸展的特点。

The substituted half-sandwich titaconece with bulky alkoxyl group [CpTiC1〓 or CpTi 〓] or indene ring can not be fluorinated by BF〓·Et〓O under the selected condition, but still coordinates with the BF〓, this coordination then enhances the steric effect that stabilizes the precursor and hinders the reduction of the Ti to the Ti species, reflected in the decrease in polymerization activity.

但是这个转化受主催化剂分子的空间位阻和聚合反应温度的影响，当主催化剂为大位阻的烷氧基取代茂钛络合物或茚钛络合物时，在一般的聚合温度下BF〓不能对它们进行氟化，但可以和其中的OR配位，这种配位进一步加剧了空间位阻，从而阻碍了活性中心的形成，导致催化活性的下降。

In this section we look at the theory behind the techniques used in rotary polishing and the effects that they have on paintwork and the results achieved.

在这里看抛光剂使用背后的理论，到底是怎么一回事，我们如何用好的抛光机和好的使用技巧来达到好的效果。

I'll dig like a psychotic rodent if I have to.

那我就帮你挖到中国去。
